Abstract

L'invention concerne les moteurs de véhicules. Le dispositif faisant l'objet de l'invention est caractérisé notamment en ce qu'il comporte une virole 9 en forme de cône tronqué, disposée entre la tuyère 2 du moteur et l'ajutage d'éjection 1 de manière que la section d'entrée, de plus grand diamètre, de la virole soit orientée vers la section de sortie de la tuyère du moteur et que la section de sortie, de plus petit diametre, de la virole soit orientée vers la section d'entree de l'ajutage d'éjection. L'invention s'applique par exemple aux moteurs d'avions utilisés dans l'aviation agricole.
